Comparative without than

Adjectives come in three forms: positive (big), comparative (bigger) and superlative (the biggest).

If the adjective has more than two syllables, we use more and most: Important, more important, the most important.

Do not use a comparative without comparing.

If you use a comparative (faster, better, cleaner, more difficult, more beautiful, more impressive, harder, smaller etc), you must compare it with something, and the linking word you need is THAN. 

So, do not write:  Poor information makes it more difficult for consumers to make more healthy and more informed choices. 

Whereas the first "more" might be justified, the next two invite a comparison that is never made.

Similarly, do not write: Living without the internet is more difficult.

Instead, write: Living without the internet is more difficult than living without your left leg.

And if you think that is overdoing it, and that the addition of a whole than clause is a pain leading to little gain, then don't use the comparative of the adjective in the first place.  

Best of all, use it very sparingly and wisely. 

Faster, smarter, better.
